Upskilling on Azure B2C custom policies — Claims transformations

Exercise 6

The customer wants to call the claim in the first page “emailAddress”. So we need to copy the claim value from “emailAddress” to “signInName”. This still allows the name to be pre-provisioned.

We could use the CopyClaim claims transformation.

Claims transformations can be input claims transformations or output claims transformations.
